Abstract

PURPOSE: To provide an intake system for engine, in which a throttle assembly in the form of a hollow cylinder is fitted in the intake pipe in the manner capable of sliding axially of the pipe and an upper portion of said throttle assembly is shaped to have a tapered surface having a predetermined inclination angle, so as to mix fuel with air effectively between a fixed valve and said inclined surface of the throttle assembly.
CONSTITUTION: Intake pipe 3 communicated to intake manifold 4 is composed of upper and lower housings 31, 32. In the intake pipe 3, there is provided a throttle assembly 10 in the form of a hollow cylinder such that it can be slidable along wall surface 35 of pipe 3 in tight contact with the same, and the throttle assembly 10 is connected to accelerator pedal 49 by means of linkage. At an upper portion of the throttle assembly 10, there is formed a tapered surface 18 having an inclination angle of about 35°W55°. Further, there is provided a fixed valve means 11 which is located at the bottom of said taper surface 18 when throttle assembly 10 is at its top dead point. The valve means 11 is shaped sharp at its end portion so as to make fuel ejected from fuel injection valve 5 flow smoothly through the valve.
